Soft hockey wheels work like an eraser, allowing you to perform "hockey stops" on a plastic floor using what are known as "soft" wheels. But, after a season or so they become hard and no longer grip the surface. I thought about experimenting with dipping the wheels ( not the bearings ) in coke or pepsi then letting that movie theater floor stickyness; hopefully take effect. But, then I guess it would slow me down and we can't have that. Are there any chemists out there that can help us out? New wheels can cost between $40 - $80 a pop.
